WOODWORKING-MACHINE.

To all whom 'it may concern:

Be it known that I, HERMAN Rnioii, a citizen of the United States,residing at township of Greenwood, in the county of Vernon and State ofWisconsin, have invented a new and useful lVoodworking- Machine, ofwhich the following is a specification.

This invention relates to that class of wood working machines in whichseveral mechanisms are combined in one machine and driven by the samepower, and more particularly a combined boring and sawing mechanism.

The invention relates specifically to the boring mechanism, its objectbeing to provide improved means for adjusting the boring mechanism tothe Work, and also to increase the eiiiciency of the mechanism, and toprovide certain novel and improved struc tural details to be hereinafterdescribed and claimed.

The invention is illustrated in the accompanying drawings in whichFigure 1 is a front elevation showing the boring mechanism in operativeposition. Fig. 2 is a plan view. Fig. 3 is a plan view of the machinewith the boring mechanism removed. Fig. 4 is an enlarged transversesectional view on the line 4 4 of Fig. 1. Fig. 5 is an enlargedhorizontal sectional view on the line 5 5 of Fig. 1. Fig. 6 is avertical section on the line 6 6 of Fig. 4. Fig. 7 is a detail of thesaw table adjustment. Fig. 8 is a section on the line 8 8 of Fig. 3.Fig. 9 is a section on the line 9 9 of Fig. 4. Fig. 10 is an elevationof the device for raising and lowering the saw table to be hereinafterdescribed.

Referring to the drawings, the supporting frame of the machine iscomposed of longitudinal side bars, and transverse end and intermediatebars, all of which are suitably connected, and arranged to support themechanism. The main drive shaft 10 of the machine is mounted in suitablebearings on the lower cross-bars of the frame. At one end of thesupporting frame is mounted a band saw 11 driven from a pulley 12 on theshaft 10, and at the opposite end of the frame is mounted a circular saw13 driven from a pulley 14 on the shaft 10. The last mentioned sawprojects through a slot 15 in' a saw table 16 comprising a leaf which ispivoted at one of its ends to one of Speccation of Letters Patent.

the top longitudinal bars 17 of the supporting frame. On the saw tableis mounted an adjustable saw gage 18.

To the top and bottom longitudinal bars 19 and 20 of the supportingframe, adjacent to the free edge of the saw table, is secured a bracket21 having a vertical recess in its outer edge, the inner wall of whichrecess is formed into a rack 22. In this recess is mounted a pinion 23which meshes with the rack 22, and has its shaft 24 projecting throughalined vertical slots 25 made in the side walls of the recess. On theouter edge of the bracket 21 are bearings in which an endless screw 26is rotatably mounted, said screw being in mesh with the pinion 23. Thescrew is fitted with a handle 27 whereby it may be rotated, and when sorotated, the pinion 23 is rotated and caused to travel up and down onthe rack 22. The pinion shaft 24 carries an arm 28 which is forked tostraddle the bracket 21, and receive the respective ends ofthe pinionshaft. The upper end of the arm carries a cross-piece 29 which isengageable with the under side of the saw table 16 adjacent to its freeedge. Upon operating the worm gearing herein described, the arm is movedupwardly or downwardly, whereby the table is raised or lowered at itsfree end.

Intermediate the saws 11 and 13, the supporting frame carries a secondcircular saw 30 which is driven from a pulley 31'ao'n the shaft 10.Located to one side of this saw, and supported on the top longitudinalbars 17 and 19 of the supporting frame, are racks 32 on which a sawcarriage 33 runs. The racks extend transversely of the machine. On thebottom of the carriage is mounted a pair of transverse shafts 34carrying pinions 35 which are in mesh respectively with the racks 32. Onthe bottom of the carriage are also mounted flanged rollers 36 theflanges of which enter grooves 37 made in the inner edges of the racks.The carriage 33 is fitted with adjustable saw gages 37a. The racks 32are removably secured to the bars 17 and 19 in order that they may betaken ofi' when the boring mechanism is to be used.

The boring mechanism is carried by a frame having sills 38 adapted to bebolted to the top bars 17 and 19 after the racks 32 have been removed,whereby said boring mechanism is mounted in proper position for use. Thesills are connected at their ends by a suitable framework 39 havingbearings 40 for a countershaft 41 extending parallel to the shaft 10 andbelted thereto.

On the sills 38 are mounted stationary guide rails 42 which extendtransversely of the machine, and on which are mounted for travel theslides 43 of a carriage which supports the spindle of the boring bit,and its associated parts to be presently described. The inner faces ofthe rails 42 have tongues which enter grooves in the contiguous faces ofthe slides 43. On the slides 43 are supported guide rails 44 extendingat right angles thereto, and lengthwise of the machine, said rails beingfixedV to the slides 43. On the rails 44 are mounted for travel slides45, the contiguous faces of said parts being provided with tongues andgrooves in the same manner as the rails and slides 42 and 43.

From the slides 45 rise the side frame members 46 of the boring machinecarriage,

said frame members being connected at their ends by the cross-pieces 47and 43 respectively. The cross-piece'48'carries a bearing 49 in which ismounted a shaft 50, said shaft being one of the members .of a sectionalshaft, the other member of which is indicated at 51. The shaft section50 is angular in cross-section for a portion of its length, andAtelescopes within the shaft section 51, the latter being tubular, itsbore corresponding tothe cross-sectional shape of the shaft section 50,so that both sections will rotate together. The shaftsections 50 and 51extend transversely of the machine, and on the section 51 is a bevelgear 52 which meshes with the bevel gear 53 on the shaft 41. The shaftsection 51 is supported in an elongated bearing 54 fitting looselybetween the frame members 46, so that the latter may be free to travelback and forth across the supporting frame of the machine. YThe bearing54 has at'one of its ends spaced ears 55 provided with alined openingsthrough which the shaft 41 extends, the gears 52 and 53 V.being locatedbetween these ears. Thelongitudinal edges of the bearing 54 Y havetongues which fit within guide grooves in the inner faces of the framemembers 46. The bevel gear 53 is splined on'the shaft 41 so that it maymove lengthwise thereon withthe boring machine carriage. At 56 isindicated a screw for adjusting the boring machine carriagetransversely. This screw is rotatably supported Vat one end in a bearingbracket at 57 secured to one of the slides 43. On one of the sills 38 isrigidly mounted a nut 57a through which this 'screw is threaded. Ascrew'58 for adjusting the carriage lengthwise is alsoV provided. Thisscrew is rotatably mounted at one of its ends in a bearing 59 carried bya cross bar 60 carried bythe slide 45, and it is threaded through a nut`61 rigidly secured to one Aof the slides 43. Both screws are providedwith suitable crank handles 62 lfor operating the same. The screw 56extends transversely of the boring machine carriage, and the screw 58extends longitudinally thereof, in view of which it will be evident thatwhen the former is operated, the carriage will be adjusted transversely,and when the latter is operated it will be adjusted lengthwise of theframe of the machine.

On the front end of the boring machine carriage is mounted a pair ofspaced. vertically disposed plates 63 connected at the top by across-piece 64, and adjacent thereto by a cross-piece 65. These twocross-pieces have alined openings in which the spindle 66 of the boringbit is mounted. The spindle is vertically disposed, and is geared to theshaft section 50 by a bevel gear 66"L on the spindle meshing with abevel gear 67 on the shaft section. The gear 66 is supported on top ofthe cross-piece 65, and is splined on the spindle so that the latter maybe lowered and raised to feed and back the boring bit. The spindlecarries a chuck 68 for attachment of the boring bit, and adjacent to thechuck, it carries a cross-head 69, mounted to slide in guide groovesmade in the inner faces of the plates 63. This crosshead is formed witha bearing box 70 which carries a shaft 71 on which are mounted pinions72 which mesh with racks 73 secured to or formed integral with the innerfaces of the plates 63. Adjacent the racks, and extending parallelthereto, the plates 63 have slots 74 in which the projecting ends of theshaft 71 work, one of said ends of the shaft being fitted with a crankhandle 75, rotation of which, by reason of the engagement of the pinion72 with the racks 73 lowers or raises the cross-head 69, and thusadvances the boring bit into the work, or backs it. The cross-head isheld on the spindle between a shoulder thereon and the chuck, as shownin Fig. 6.

In the slot 74 is mounted a cross-bar 76 which is in the path of thebearing box 70, in the downward movement thereof, and therefore servesas a stop for the bit, and thus regulates the depth of the hole to bebored. The cross-bar 1s adjustably mounted in the slot, and has at itsends reduced screwthreaded portions to receive wing nuts 77 whereby itis clamped in adjusted position.

To the bearing box 70 is fastened a resilient strip 78 having at itsfree end a pair of oppositely presented arms 79 engageable with notches80 in the front edges of the bars 63, for holding the bit in elevatedposition while the work is being adjusted. The strip is provided with ahandle 81 for operating it. The work to be bored is supported onbrackets 82 mounted on the front of the supporting frame of the machine.

By the construction and arrangement of parts herein described, themachine can be quickly changed from a sawing to a boring machine, andthe boring mechanism is given a wide range of adjustment, the meanswhereby the adjustments are effected, being simple in construction, andeasily controlled by the operator.

What is claimed is:

l. In a boring machine, a supporting frame, spaced plates thereon, saidplates having alined slots, a cross-head slidable between the plates, aboring spindle carried by the cross-head, a cross-bar adjustably mountedin the slots in the path of the crosshead, for limiting the movementthereof in one direction, said cross-bar projecting at its ends from theslots, and being reduced and screw threaded, nuts screwed on saidthreaded ends for holding the cross bar at adjustment, means foroperating the crosshead, and driving means for the spindle.
